Idealized facies of bottom current deposits (contourites) have been established for fine-grained contourite drifts in modern deep-marine sedimentary environments. Their equivalent the ancient record however are only scarcely recognized due to weathered nature most outcrop. Facies related erosional elements (i.e. channels) depositional systems not yet properly and outcrop appear non-existent. To...

The Uruguayan continental margin (UCM), located in the Southwestern Atlantic margin’s subtropical region, is positioned a critical transitional region regarding global ocean circulation (Río de la Plata (RdlP) outflow and Brazil-Malvinas Confluence), as also reflected seafloor features (northernmost distribution of large depositional contourite system RdlP paleovalley). This complex oceanograph...

The Western Mediterranean Deep Water (WMDW), on its way out toward the Atlantic Ocean, has favored formation of contourite drifts in Alboran Sea (SW Mediterranean) since opening Strait Gibraltar. Resolving nature these deposits is crucial for reconstructing WMDW variability at a millennial scale, deciphering bottom current paleo-velocity, and establishing paleoclimatic implications over last 25...

Synchronous interaction between bottom currents and turbidity has been reported often in channel–levée systems where the thickness of exceeds that levées. Such interplay along-slope down-slope sedimentary processes is one mechanisms by which ‘mixed turbidite–contourite systems’ can originate. However, flow over large areas seafloor, including continental slopes characterized deeply incised subm...

An uncommonly continuous Lower Jurassic (uppermost Sinemurian and Pliensbachian) section (Llanbedr (Mochras Farm) Borehole, Cardigan Bay Basin, UK) comprises hemipelagic calcareous mudstone, wackestone/siltstone subordinate packstone/sandstone. Some beds show bigradational grading, their sedimentary structures are typical of contourite drift facies. On the basis long-term persistence stability ...
